Charge the batteries at least once every six months,if they are stored at 25 .0C

Float Service:

Equalisation charging is recommended once every 3 to 6 months using.

Discharge 100% rated capacity.

Charge 2.35v/cell constant voltage, maximum 0.3CA 24hrs.

Cyclic Service:

Temperature compensation for varying temperatures:

-Charge voltage -3mV/Cell/degC from 25degC norm.

Equalisation charge:

It is recommended to check battery/Float voltage each month.

The service life of your battery will be affected by:

-The number of discharge cycles, depth of discharge, ambient

temperature and charging voltage.
